Application filed May 16, 1919. Serial No. 297,607.

To all whom it may concern:

Be it known that I, MURRAY HENRv, a citizen of the United States, and a resident of San Antonio, in the county of Bexar and State of Texas, have invented new and useful Improvements in Burners, of which the following is a specification. V

This invention relates to oil burners of the superheating type and has particular references to that class of burners adapted to be used in connection with locomotives and other power units requiring the generation of steam as a propelling agent.

An important object of the invention is to provide in a device of the above mentioned character a means whereby the oil or fuel employed may be sufficiently heated prior to its ejection therefrom to facilitate a complete combustion.

Another object of the invention is to provide in a device of the character described a means whereby steam or other fluid may be injected into and adequately mixed with the fuel simultaneously with the ejection of the fuel from the device.

A further object of the invention is to provide in a device of the above mentioned character a means whereby the fuel may be completely atomized upon its being released or ejected from the device as a whole.

A further object of the invention is to provide in a device of the above mentioned character a means whereby an auxiliary atomizing effect may be effected in connection with a prior atomizing of the main supply of fuel.

Other objects and advantages of the invention will be apparent during the course of the following description taken in connection with the accompanying drawings.

In the drawings, forming a part of this specification and wherein like numerals are employed to designate like parts throughout the same,

Figure 1 is a top plan view partly in section of the device embodying my invention,

Fig. 2 is a vertical longitudinal sectional view taken on line 22 of Fig. 1,

Fig. 3 is a vertical longitudinalsectional view taken on line 3-3 of Fig. 1,

Fig. 4: is a transverse sectional view taken on line 4-4 of Fig. 3,

within the fire box of a locomotive and suit- I ably supported or retained therein by means of ears 6 provided with openings 7 adapted to receive bolts or other fastening instrumentalities. The superheating chamber 5, as clearly shown in Fig. 6, comprises upper and lower walls 8 and side walls 9. Between the upper and lower walls 8 there is arranged a substantially Ushaped partition 10 terminating at its ends in proximity to the forward end of the chamber 5 as clearly shown in Fig. 1. The partition 10, as is apparent, divides the heating chamber 5 into sub chambers 11 and 12-12. The subchamber 12 is maintained in communication with a liquid fuel conveying pipe 13 throu h an opening 1d, clearly shown in Fig. 2. T e liquid fuel conveying pipe 13 is adapted to be connected to a suitable source of supply of liquid fuel, not shown. This source of fuel supply may be incorporated as a part of the present day locomotive tender if the device embodying my invention is used in connection with locomotives or it may be a stationary tank suitably located if the device embodying my invention is used in connection with power plants of the stationary character such as those plants which are used for the production of heat, power, light, etc. The heating chamber 5, as clearly shown in Fig. 1, is connected to a secondcha-mber indicated as a whole by the numeral 15. This chamber is divided into sub-chambers 16, 17 and 18. The chambers 16 is maintained in communication with both of the sub-chambers 12 as clearly shown in Fig. 3. The heated liquid passing from the heating chamber 5 follows the course shown by the arrows of Fig. 3 entering the chamber 16 whereupon it passes upwardly through an elongated opening 19 and upon escaping from the opening 19 is atomized and sprayed into the atmosphere directly over the heating chamber 5 as will hereinafter be more fully described. The chamber 18 extends forwardly an appreciable distance and terminates in proximity to the opening 19 as clearly shown in Fig. 2.

The chamber 18 is supplied from a suitable source, not shown, with steam flowing in the direction indicated by the arrows therein of Fig. '2. A part of the steam entering the chamber 18 is deflected through a narrow opening 20 directly beneath an elongated deflector 21 which is secured in position by means of bolts as shown at 22. The steam thus passing through the elongated opening- 20 under pressure consequently atomizes the heated liquid fuel passing upwardly through and out of the elongated opening 19. The heated fuel when passing from the opening 19 is of a more or less foamy or boiling nature, thus because of th1s condltion not only does it make posslble its being easily atomized or sprayed forwardly but it also facilitates its complete combustion. The steam acting under pressure as above described serves not only to atomize the superheated liquid fuel but also as a means to facilitate complete combustion in that due to the intense heat of the burning liquid the molecules of steam are broken up into constituents of free oxygen and hydrogen, the

oxygen serving to support combustion of the liquid fuel while the hydrogen burns with intense heat.

While the main portion of the heated fuel isatomized upon its being ejected from the passage 19 there is, however, a limlted quantitymoved forwardly in an unatom1zed condition. As a means for atomizing this superfluous quantity which would otherwise run down on to the upper side of the heating chamber 5 I employ the auxiliary chambers 17 which communicate with the chamber 18 as shown at 23. The chambers 17 extend longitudinally with the chambers 16'and 18 and communicate with a transversely arranged duct 24, the steam passing from the chambers 18 into the duct 24 in the direction of the arrows shown therein in Fig. 1. The duct 24 is partially closed by a head 25 similar'to the deflector 21, it differing however, in that its construction permits the opening 14. The liquid fuel upon entering- V the chamber 11 is heated by the flame of the burning liquid above the heated chamber 5. The liquid fuel passes out of the chamber 11 and into the chambers 12 in the direction of the arrows therein as shown in Fig. 1. The

fuel upon entering chambers 12 passes backwardly entering the elongated opening 19 in a heated condltion. The superheated fuel passes upwardly and out'of the elongated opening 19 whereupon steam under pressure passing from chamber 18 through the opening 20 is brought into contact with the heated liquid in a foamy condition. As a result of the contact of the steam under pressure withthe heated fuel an atomizing effect is produced whereupon the major portion of the fuel is sprayed forwardly and burned with an intense heat. The intense heat is due partially to the heated condition of the liquid fuel which facilitates complete combustion and also to the ultimate breaking up of the steam into its constituents of hydro-' gen and oxygen, theoXygen going to support combustion while the hydrogen burns with intense heat. A portion of the unatomiz ed liquid is driven forwardly by the steam issuing from the opening 20 but this unatomized liquid is finally brought into contact with the steam issuing from the opening 26 under pressure whereupon a complete atomizing. effect of the total amount of fuel passed through the heated chamber 5 is produced.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the. shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having 7 thus described my invention, what I claim as new and desire to secure and protect by Letters Patent of the United States, is:
